ScienceDaily: Engineers Create Gecko-inspired, High-friction Micro-fibers:

"High friction materials can prevent sliding under high loads or steep inclines. The researchers found that the synthetic array of polypropylene fibers could hold a quarter to a glass slide inclined at an 80 degree angle, yet is not 'sticky' like adhesive tape. The fibers, packed 42 million per square centimeter, each measured a mere 20 microns long and 0.6 microns in diameter"
